Tree Risk Assessment Canberra

When Visual Inspection Isn't Enough

Most tree assessments rely on what an arborist can see. Although a trained eye picks up most warning signs, some of the biggest risks are internal decay, cavities, cracks and structural defects which are hidden inside the tree. As a result, standard visual inspection alone can miss what matters most.

Canopy provides advanced tree risk assessment across Canberra, the ACT and surrounding NSW. In particular, our specialist 2D and 3D sonic tomography lets us investigate the internal condition of a tree without drilling, damage or destructive testing. Furthermore, the information gained can support tree retention, construction planning, risk management and long-term asset management.

Whether you're managing a single significant tree or an extensive tree population, our diagnostic services provide the evidence to make informed, defensible decisions.

Why It Matters

What Sonic Tomography Can Reveal

Sonic tomography works by placing sensors around the tree trunk or limb, then tapping each sensor to send stress waves across the wood. Where wood quality is high, the waves travel quickly. Where decay is present, they slow down. Where wood is missing (a cavity or crack), the waves have to travel around it, taking noticeably longer to reach the other sensors.

As a result, the technology can indicate the probable presence of internal decay, cavities, cracks and other structural features that visual inspection alone can't detect. In particular, it helps arborists, engineers and property owners understand what is really happening inside a tree before making retention, pruning or removal decisions.

This is especially valuable for high-value trees where retention is preferred, or for trees near buildings, roads or high-use areas where getting the decision right actually matters.

2D Sonic Tomography

2D Sonic Tomography Explained

2D sonic tomography provides a cross-sectional assessment of the internal condition of a tree stem or major scaffold limb at a selected testing height. Using specialised sonic technology, measurements are taken around the circumference of the tree to produce an image representing variations in wood condition. Areas of reduced sonic velocity may indicate altered wood properties consistent with decay, cavities, cracks, or other internal features.

2D testing is often suitable for suspected internal decay, hollow trees, crack investigations, and trees with visible defects. In addition, it supports Visual Tree Assessments (VTA), risk assessments, baseline condition monitoring, and homeowners seeking further investigation before making a removal decision.

Because the assessment is non-invasive, we can capture the evidence without drilling or damaging the tree.

3D Sonic Tomography

3D Sonic Tomography Explained

3D sonic tomography builds on the information obtained from a single cross-section by assessing multiple levels of the stem or structural limb. As a result, we can create a three-dimensional representation of the tested section, giving a clearer understanding of the vertical extent of internal wood alteration and structural defects.

This assessment is particularly valuable for high-value trees where retention is preferred, and for management decisions that require a greater level of confidence than a 2D scan can provide. For example, significant or heritage trees, council-managed trees, trees near buildings or high-use areas, development applications, complex structural defects, and long-term monitoring programs.

Furthermore, 3D testing gives you the evidence to defend a retention decision in front of council, insurers, or a court, when the situation calls for it.

"

I recently had my ageing liquid amber tree assessed by Canopy Tree Experts using a tomograph. Paul had a good understanding of the technology and took the time to explain how the tomograph works and what the results would mean for the health of my tree. The scan provided a clear and detailed assessment of the health of the tree, allowing us to make an informed decision about future maintenance. I appreciated the non-invasive nature of the test, no drilling, no damage, just accurate data. Overall, I found the use of the technology reassuring. I'd highly recommend this technology to anyone who wants a reliable assessment of their tree's structural integrity.

Who This Is For

Who Uses Tree Risk Assessment

Tree risk assessment with sonic tomography is a specialist arboricultural service. In particular, it's most valuable when decisions about a tree carry significant consequences.

Councils & Asset Managers

Evidence-based assessment for council-managed trees, heritage listings, and long-term asset management programs.

Developers & Town Planners

Structural evidence for development applications, especially where protected or significant trees exist on site.

Homeowners

Homeowners investigating a suspected defect, a hollow trunk, or seeking further evidence before deciding on removal.

Insurance & Legal

Independent, evidence-based assessments for insurance claims, boundary tree disputes, and risk-related tree matters.

Schools, Universities & Hospitals

Risk assessment for significant trees on high-use sites where safety and duty of care are non-negotiable.

Engineers & Builders

Design-stage assessment where existing trees near construction need to be evaluated for structural integrity.

Reports & Deliverables

What You Receive at the End

Every tree risk assessment ends with a written report. In particular, the report combines the tomogram outputs from the assessment with professional arboricultural interpretation, giving you evidence and practical recommendations tailored to each tree and site.

Furthermore, the report is suitable for councils, engineers, builders, and private clients. As a result, it can support tree retention decisions, construction planning, Arboricultural Impact Assessments, risk investigations, development approvals, and insurance investigations.

We'll discuss the scope and format of the report as part of the initial conversation, so you know exactly what to expect before the assessment begins.

How It Works

Our Tree Risk Assessment Process

Tree risk assessment is a specialist service, so the process runs a little differently to standard tree work. Here's how a typical job runs from first call through to delivered report.

1

Initial Discussion

Call or send us a message describing the tree, your concerns, and what you're trying to establish.

2

Scope & Quote

We confirm the scope, decide whether 2D or 3D is right for the job, and provide a written quote.

3

On-Site Assessment

We attend site, set up the tomography sensors, and capture the readings around the tree.

4

Report & Recommendations

You receive a written report with tomogram outputs, interpretation, and practical recommendations.

Advanced tree diagnostics are not a service most tree companies offer. Furthermore, doing it well requires the right equipment, arboricultural expertise, and the ability to present findings in a way that non-arborists can act on. Canopy brings all three.

Advanced Diagnostic Technology

2D and 3D sonic tomography purpose-built for tree assessment. Non-invasive, evidence-based, no drilling.

Arboricultural Expertise

Assessments delivered by a qualified team with the arboricultural experience to interpret the data, not just capture it.

Independent & Evidence-Based

Reports and recommendations grounded in the data captured on the day. No guesswork, no shortcuts.
